Abstract
With the huge demand for energy storage, among several metal oxides, MoO3 has been excellently focused due to its high theoretical capacity (1117 mA h g−1), because of its high voltage and energy storage. Its poor conductivity and higher volume variations at the time of lithiation/de-lithiation are the major obstacles in realizing this high capacity. To overcome this problem, we have synthesized MoO3 nanoparticles of different fuel ratios by combustion method using tamarind seed powder as a novel fuel and we have shown that by increase fuel ratio carbon content increases where it acts as a shielding for the battery performance. The prepared material is subjected to various characterization techniques to get information on structural purity, morphology, and optical property. XRD pattern shows orthorhombic MoO3 phase where Raman and IR spectroscopy shows Mo-O vibration. HRTEM shows the interplanar distance of 6.7 Å. CHN analysis shows the percentage of carbon in the final product and BET surface area was found to be 9.3065 m2g-1and UV-DRS were analyzed for the prepared sample. The prepared optimised material (MoO3 1:1) exhibits the reversible initial discharge specific capacity of (669 mA h g−1) and its stabilized specific capacity reached (445 mA h g−1) after 100 cycles at 0.1C.
